RIVET SETTING AND DISPLACIN'G TOOL.

Application filed September 28, 1909, Serial No. 520,051.

To all whom it may concern:

Be it known that I, JOHN W. THRASHER,

a citizen of the United States, residing,at

\Vaco, in the county of McLennan and State 5 of Texas, have invented certain new and useful Improvements in Rivet Setting and Displacing Tools, of which the following is a specification.

This invention relates to tools for setting new rivets and displacing defective rivets from buggy bow-sockets, and my object is to produce .a tool of this character which operates efliciently and reliably and which is of convenient size and form to be handled easily.

A further object is toproduce a tool of this character of simple, strong, durable and inexpensive construction.

To 'these ends the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which:

Figure 1, is a of a tool embodying my invention. Fig. 2, is an end view of the same. Fig. 3, is a section on the line IIIIII of Fig. 1.-

In the said drawing, 1 indicates a substantially cylindrical anvil, from opposite sides of which project a setting-up post 2 having a cavity 3 in its end, and a T-shaped handle 4, the ends of the head of the handle terminating in arcuate portions 5 and 6 forked at their ends 7 and 8 respectively. The arms of the forked end 7, are provided with alined openings 9 wherein reciprocably fits a rivet-displacing punch 10 disposed coaxially with respect to the anvil, said cross-pin or shoulder 11 against which the outer end of a coil spring 12 bears, the opposite end of said spring bearing against the inner arm of said fork and holding the punch which is tapered at 45 its front end, normally withdrawn from the The ad acent end of said anvil is provided with a cavity 13 having communicating passages 14 and .14 through which a defective rivet may respectively enthe cavity. The passage la is a lateral passage corresponding in depth to socket 13 and extending from the latter through the periphery of the anvil so that a bow socket may be fitted against the 5 end of the anvil and the end of a rivet in anvil.

Specification of Letters Patent.

central longitudinal section Patented Mar. 2, 1915.

Renewed November 16. 1914. Serial No. 872,496. said bow socket may be caused to enter the anvil by being moved 'sidewise throu h the passage 14 into the socket 13 and in ongitudinal alinement with the punch 10. The forked end 8 of the handle is also provided with openings 15 coaxial with the anvil, and mounted reciprocably in said openings is a plunger 16 having a concave-faced head 17 at its inner end and a cross-pin or shoulder 18 between the arms of the fork to receivethe back pressure of a spring 19 which bears at its front end against the inner arm of the fork for the purpose of holding the plunger normally withdrawn and spaced from the adjacent end of the anvil and the recess 20 therein.

In use, the device is grasped by the handle and the post 2 is pressed against a rivetwith the head of the latter occupying cavity 3to force the same through bow-sockets until the front end of the rivet is exposed. The position of the tool is then shifted so as to dispose the anvil and the plunger at opposite sides of the bow-sockets and rivet extending therethroug the said exposed end of the rivet fitting in recess 20 and the head of the rivet in the concave-faced head 17 of the plunger. When the parts are thus arranged the outer end of tapped with a hammer for the purpose of upsetting or heading the inner end of the rivet and thus securing the bow-sockets reliably together, the spring returning the plunger to its original position.

In the event that a rivet engaging a bowsocket is broken or injured, the tool is arranged with its anvil and the forked end 7 of the handle at opposite sides of the socket, the headed end of the rivet being fitted in cavity 13 by way of passage 14, by preference. The punch 10 is then given a sharp tap with a hammer to displace the broken or injured rivet and drive it from the bowsocket into the cavity 13 from which it falls by way of passage 14, the punch being restored to its original position by the spring 12 after each advance under the impact of the hammer.

From the above description it will be apparent that T have produced a rivet setting and displacing tool embodying the features of advantage enumerated in the statement of the object of the invention, and I wish it to be understood that changes in the form, proportion, detail construction and arrangethe plunger isment of the parts may'he made without deg parting from the spirit and scope of the ap ended claims. y

aving thus described the invention what I claim as new and desire to secure by Letters-Patent, 1s-

- 1. A rivet-.displacing tool, comprising a handle member "carrying an anvil and a punch reciprocablein alinement with sa d anvil and normally retracted therefrom, said anvil being provided with a socket extendfhandle member carrying an anvil and punch reciprocable in alinementwith said 2'. A rivet-displacing tool, comprising a anvil and normally retracted therefrom, the face of .said anvil being provided with a socket in alinement with said punch, the inner-end of said socket communicating through a passage with the side of the anvil, said socket also having a lateral opening through the side of the'anvil extending the full depth of the socket.

In testimony whereof I afiix my signature,
